Title: Improvements in or relating to electric control systems
IPC: E21C31/12
Filed: 1925-10-02
Abstract: 257,425. Wade, H., (Sullivan Machinery Co.). Oct. 2, 1925. Electromagnetic switches. - In the control of motors, working in a dangerous atmosphere (for example coal-cutting machines) by means of an electromagnetically-controlled switch located at the gate-end, the switch is operated to control the motor by means of a pilot operating circuit incorporated with the trailing cable and the operation is produced by varying the induction in the field circuit or by acting inductively on it without ever breaking the circuit. In the arrangement shown in Fig. 2, the gate-end switch 14 is rocked into the closed or open position by the attraction of the core 18 or 17 by one or other of the equal windings 20, 19. These windings are connected to one another and to a similar pair of windings 22, 21 in the manner shown, and the midpoints connected across one of the phases so that equal currents normally flow in them. The balance may be disturbed by hand actuation of the arm 28, located on or near the motor, which introduces one or other of the cores 25, 26 into the coils 21, 22 and alters the current in one of the coils 19, 20 so that the gate-end switch is operated. This switch may be a star-delta starter. Instead of acting directly, the coils 19, 20 may serve to energize one or other of two coils which are energized from the supply and serve to operate the gate-end switch more powerfully. In a modification, Fig. 4, instead of upsetting the balance by means of cores introduced into solenoids, a _coil 42 mounted for hand-control on an arm 45 is connected across the supply and when moved over serves to increase the induced current in one of the coils 37, 38 and reduce it in the other.

[Class 64 (iii).] A heat exchanger, such as a radiator for cooling liquids, consists of units each formed by placing together a pair of metal sheets 3, each formed along two opposed edges with corrugations and with strip-like elevations 5 near and parallel to these edges, so that when two plates are placed together, the corrugations define nozzles 4 communicating with the spaces 1 between the plates through which a fluid such as air passes, and when the units are placed together the elevations 5 on adjacent units space them apart to afford passages 2 for the other fluid which may be water. By this construction blind hexagonal cells 8 are formed among the nozzles 4 and these may be perforated at their inner ends to cause them to act as additional nozzles. Additional elevations 6 may be provided parallel with the elevations 5 and between these, depressions 9 may be provided extending into the air passages 1 to create turbulence. Certain of these depressions may be deep enough to contact with the corresponding depressions in the adjacent sheet, as shown in Fig. 6. In another construction, transverse ribs 11, Fig. 8, are provided between the elevations 5, the ribs contacting with corresponding ribs on the adjacent sheet. In the construction shown in Fig. 16, depressions 12 alternate with depressions 9, and elevations 13 are provided projected into the water passages 2. These elevations 13 may be provided in the other constructions.

Abstract: 1432136 Producing sulphur-free gas EXXON RESEARCH & ENG CO 24 May 1973 [25 May 1972] 24739/72 Heading C5E Substantially sulphur-free gas is produced from sulphur-containing fuel by passing the fuel into a bed of sulphur-fixing material whereby sulphur from the fuel is fixed in the material as sulphur-containing, sulphur-fixing material and a substantially sulphur-free fuel or fuel gas or flue gas passes out of the bed, subjecting the sulphur-containing sulphur-fixing material to a regeneration process thereby to regenerate the sulphur-fixing properties of the material with the liberation of sulphur and/or sulphur compounds, re-using regenerated sulphur-fixing material to fix sulphur from further quantities of fuel, and passing the liberated sulphur and/or sulphur compounds and an oxygen-containing gas into a bed of sulphur-retaining material whereby sulphur and/or sulphur compounds chemically react(s) with, and is or are retained in, the sulphur-retaining material. The sulphurfixing and sulphur retaining material comprises an alkaline earth metal oxide and/or a thermal precursor thereof, examples of which are given. The contact temperature of the liberated sulphur and/or sulphur compounds and of the sulphurretaining material is 800‹ to 950‹ C. The sulphur-retaining activity of the bed is maintained by adding fresh sulphur-retaining material to the bed and discarding material in which sulphur is retained. The gas mixture leaving the sulphur - retaining bed is recycled to the bed of sulphur-fixing material in order to fix any sulphur and/or sulphur compound which has not been retained in the sulphur-retaining bed. The sulphur-containing fuel is passed into the bed of sulphur-fixing material substantially continuously and some sulphur-fixing material is withdrawn from the bed, subjected to the regeneration process in a regeneration zone, and recycled to the sulphurfixing bed for further use whereby to maintain the sulphur content of the sulphur-fixing bed at a level which is no more than 7 wt. per cent of the bed. The temperature of the sulphurfixing bed during sulphur-fixing to 800‹ to 1050‹ C. and during regeneration is 1000‹ to 1150‹ C. When the sulphur-fixing is performed under nett reducing conditions, the regeneration process is performed under nett oxidizing conditions, and when the sulphur-fixing is performed under nett oxidizing conditions, the regeneration process is effected under reducing conditions. Reference has been directed by the Comptroller to Specifications 1,336,563 and 1,183,937.

Title: Travelling wave amplifier tube
IPC: H01J25/44
Filed: 1959-07-22
Abstract: 922,113. Travelling-wave tubes. RADIO CORPORATION OF AMERICA. July 22, 1959 [Aug. 5, 1958], No. 25213/59. Class 39 (1). A travelling-wave tube has a number of radially-cut discs 56, Fig. 2a, arranged within a conductive tube 20, Fig. 1, so as to form a number of comb-like delay lines extending axially along the tube and spaced circumferentially. An electron beam is caused to travel helically around a central conductor 36 so that individual electrons interact successively with teeth of circumferentially-adjacent combs. Intermediate discs 62, Fig. 3a, are arranged between each disc 56 and are provided with short projections 64 which bring the axial combs into the propagating condition (radial depth of slots #/4 or less) while leaving the lines formed by each circumferential set of teeth in a non-propagating condition (radial depth of slots between #/4 and #/2). Thus by a suitable input circuit 49 waves may be launched on each comb which are in opposition on adjacent combs and do not exchange energy circumferentially. The electrons, however, in space-harmonic fashion, see a synchronously-travelling wave at each tooth traversed in their helical path and give up energy to the waves for delivery to output circuit 55. The combs may alternatively extend outwardly from the central conductor and the beam then travels outside them. The input circuit consists in a cavity 49 fed by line 48 and one wall of which consists in a disc 50, Fig. 5a, with half the number of teeth so that only alternate combs are excited in phase; the output circuit 55 is similar. Choke slots 70 prevent leakage into the gun region. Cathode 24, positive grid 28, and anode 34, in conjunction with lower voltage central conductor 32 produce the annular helically-moving beam 22, which is finally collected by collector 18. The central conductor 36 is supported on conductor 32 and on rod 46 slidably engaging the collector 18.

Filed: 1946-08-26
Abstract: 639,462. Labelling-machine.. DETREZ, R. Aug. 26, 1946, No. 25372. Convention date, Aug. 25, 1945. [Class 73] [Also in Groups XVII, XXIII, XXIX and XXX]  In a machine for filling, closuring and labelling bottles and like receptacles, receptacle supports which are conveyed with a rotary platform or conveyer are raised and lowered at the various operating stations when each of several fixed raising and lowering apparatus incorporated in the machine at the several operating stations is brought into temporary and periodic connection with the said supports. As shown, when a vertically-slidable bottle support 22 carried by an intermittently moving chain 17 pauses at a labelling station, a connecting member 29 fixed to the bottle support engages slidingly the head 28 of a hydraulic plunger 25 which rises during the pause to lift the bottle, which has previously been filled and sealed, against a stop 24 so that labelling members 20 can apply a label at a fixed distance from the bottle top. Bearing points 32, 32<SP>1</SP> and 33, which may be of rubber, receive transverse labelling pressure. Plunger 25 falls, and chain 17 moves forward, the bottle subsequently pausing at a station where the label is smoothed. The bottle supports may be carried on a rotary table instead of a chain ; either chain or table may move continuously instead of intermittently, in which case the bottle, supports are raised and lowered during their temporary sliding connection with the lifting means. Liquid may be supplied under pressure to the hydraulic cylinders at the various operating stations through a distributor such as is described in Specification 638,978, [Group XXIX]. The raising and lowering movements may be effected mechanically instead of hydraulically.
